Storing and Packaging

Finally, it is important to mention the widely distributed and abundant elements sodium, potassium, calcium, magnesium, aluminum, silicon, and iron. These are present to some extent in the vast majority of chemical products and, although not an infallible guide, their concentrations indicate the degree of purification of a chemical and the care with which it has been handled, stored, and packaged. 

Critical to the successtlil completion of this process are the software tools required to store and analyse the inspection and related data. This is a major task and to achieve this OIS has produced, in conjunction with a major specialist technical software provider, the Asset Condition Evaluation Tool (Acet). Acet is a comprehensive suite of programs which draws on the extensive experience of engineers working in this field for many years, to provide a readily usable and highly auditable package for this application. 

The processing operations for fluid or manufactured milk products include cooling, centrifugal sediment removal and cream (a mixture of fat and milk semm) separation, standardization, homogenization, pasteurization or sterilization, and packaging, handling, and storing. 

Gumylphenol. -Cumylphenol (PGP) or 4-(1-methyl-l-phenylethyl)phenol is produced by the alkylation of phenol with a-methylstyrene under acid catalysis. a-Methylstyrene is a by-product from the production of phenol via the cumene oxidation process. The principal by-products from the production of 4-cumylphenol result from the dimerization and intramolecular alkylation of a-methylstyrene to yield substituted indanes. 4-Cumylphenol [599-64-4] is purified by either fractional distillation or crystallization from a suitable solvent. Purification by crystallization results in the easy separation of the substituted indanes from the product and yields a soHd material which is packaged in plastic or paper bags (20 kg net weight). Purification of 4-cumylphenol by fractional distillation yields a product which is almost totally free of any dicumylphenol. The molten product resulting from purification by distillation can be flaked to yield a soHd form however, the soHd form of 4-cumylphenol sinters severely over time. PGP is best stored and transported as a molten material. 

Bromothiophenes, if not stored and treated correcdy, may decompose, Hberate HBr gas, and lead to pressurizing of containers. Prior treatment with alkah, avoiding metal contaminants, and keeping a cool temperature can avert any problems. Acylthiophenes are transported under U.N. No. 2810, Toxic Hquids, organic, N.O.S., Class 6.1, Packaging Group 111. 

Assuming that herbal drugs are going to be used medicinally, the same care will be taken regarding their storage and packaging as with any other medicine. There are not many indications to be found in the pharmacopoeias as to how drugs should be stored. 

While it is impossible to describe a system of storekeeping and distribution suitable for every site, there are certain essential principles which should be adhered to if cleanliness, order and economy are to be maintained. How these principles should be applied is for individual management to decide. The keynote, however, should be simplicity. A storekeeper familiar with both grades and needs should control distribution. While the lubrication schedule for any particular unit is generally the concern of the operator, the storekeeper must equally be aware of it and have a comprehensive list of the different grades, their applications, quantities, daily and other periodic needs. On such a basis he will be able to requisition and store the necessary lubricants in the most convenient and economic quantities and packages, and ensure that supplies are used on a first in, first out basis. 

Condensation may lead to corrosion when components are placed in relatively impervious wrappings in warm and humid workrooms or stores and then transferred to cold surroundings, and this should be taken into account in choosing the packaging technique. 

Small stores for miscellaneous products must allow for random stacking of a variety of different packages. The storage density may be between 100 and 450 kg/m when the store is fully loaded, allowing for access passages. A closer estimate could be made if probable loadings and package shapes were known [29, 33]. 

This aromatic alcohol has been an effective preservative and still is used in several ophthalmic products. Over the years it has proved to be a relatively safe preservative for ophthalmic products [138] and has produced minimal effects in various tests [99,136,139]. In addition to its relatively slower rate of activity, it imposes a number of limitations on the formulation and packaging. It possesses adequate stability when stored at room temperature in an acidic solution, usually about pH 5 or below. If autoclaved for 20-30 minutes at a pH of 5, it will decompose about 30%. The hydrolytic decomposition of chlorobutanol produces hydrochloric acid (HC1), resulting in a decreasing pH as a function of time. As a result, the hydrolysis rate also decreases. Chlorobutanol is generally used at a concentration of 0.5%. Its maximum water solubility is only about 0.7% at room temperature, which may be lowered by active or excipients, and is slow to dissolve. Heat can be used to increase dissolution rate but will also cause some decomposition and loss from sublimation. Concentrations as low as 0.125% have shown antimicrobial activity under the proper conditions. 

The section on components deals with all materials that may be used in the manufacture, processing, and packaging of drug products, plus materials used for maintenance of the building and equipment. They must be stored and handled in a safe, sanitary, and orderly manner. These precautions are needed to prevent mix-ups and cross-contamination of drugs and drug products. All items should be held until they have been sampled and tested according to the company s specifications and not released until the tests have been completed. In this section it is required that ... 

If the product is sold in different size containers, it may be stored mainly in bulk quantities and packaged after the receipt of a customer s order, or it can be packaged immediately after it is made. The type and amount of storage will be affected by the decision. 

In practice, these technical details of Implementation are of the least Importance to the user. A multitude of packages are now available for a wide range of computer systems and the selection of a DBMS for a particular application should be based mainly on the criteria of ease of use and the features required for the particular application. Consideration must also be made of the operating speed, both of the DBMS package and of the computer and its storage system, particularly in the case where large amounts of data must be stored and searched. 

As a typical pattern of a multipurpose batch plant, the authors consider a plant with multiple floors that produces various products (e.g., fine chemicals or dyes) in batches and/or semicontinuously. Raw materials are entered into premixing devices and placed together in a reactor where the chemical reaction takes place. The resulting product is separated from the mother liquor by a filter press and then packaged in various types of packaging. The mother liquor is stored and eventually recycled. The same product may even take different paths through the plant by use of alternate devices or production lines.
